What does SAFEX stand for?

SAFEX stands for the South African Futures Exchange. It was acquired by the JSE in 2001 and now operates as the JSE's derivatives market, but the name SAFEX remains in everyday use for the agricultural-commodity side of that market, where white maize, yellow maize, wheat, sunflower seed and soybean futures and options trade.

What is the difference between import parity and export parity?

Import parity is the landed cost of bringing an equivalent tonne of grain into South Africa — the world price plus freight, insurance, port handling, duties and inland transport. It acts as the practical ceiling on the local price. Export parity is the net price a South African seller could realise by exporting — the world price at destination less freight, port and inland transport costs. It acts as the practical floor. SAFEX prices normally trade in the band between the two.

What is basis risk in a grain hedge?

Basis is the difference between the physical price at a specific location and the futures price. A futures hedge removes flat price risk but not basis risk, because transport, storage, local quality and regional supply and demand still move the local price relative to the exchange. This is why a hedge should be structured around the hedger's actual delivery point, transport route and storage position rather than in the abstract.

Why does a hedge that is working still require cash?

Futures positions are marked to market daily, so gains and losses settle in cash each day rather than at expiry. A producer who has sold futures against a growing crop will be called for variation margin whenever the market rallies, even though the value of the unsold crop is rising at the same time. Planning for that cash cycle is part of running a hedging programme.

Can I trade SAFEX without a broker?

No. SAFEX is accessible only through a JSE-member broker. You open a trading account with the member, complete the regulated KYC process, and then trade either through the broker's dealing desk or by self-executing on a platform the broker provides. Applied Derivatives has been an independent JSE member since 2002 and serves both South African and international clients.

SAFEX Glossary — Grain Futures, Options & Hedging Terms Explained

The terms that come up on a South African grain-derivatives desk, defined plainly — from mark-to-market and margin through to basis, parity, and the release calendar that moves the market.

SAFEX is where South African grain price risk is priced and transferred. The vocabulary around it is largely inherited from international futures markets, but several of the terms that matter most here — parity, silo receipts, delivery points, the CEC calendar — are specific to how the South African market actually works. This page defines both.

It is a reference, not advice. If a definition raises a question about your own position, the desk is on info@derivative.co.za.

The market

SAFEX

The South African Futures Exchange. Since its acquisition by the JSE in 2001 it has operated as the JSE's derivatives market, and the name SAFEX remains in everyday use for the agricultural-commodity side of that market — where white maize, yellow maize, wheat, sunflower seed and soybean futures and options trade. SAFEX can only be accessed through a JSE-member broker.

White maize and yellow maize

The two maize contracts traded on SAFEX. White maize is predominantly milled for human consumption in South Africa and the region; yellow maize goes largely into animal feed. They are separate contracts with their own supply and demand, and the spread between them is a traded relationship in its own right.

Delivery month (contract month)

The calendar month in which a futures contract expires and delivery obligations fall due. South African grain contracts trade in a fixed cycle of months chosen to sit around the local production and marketing season, and the nearest of these is referred to as the front month.

Delivery point

A silo location approved by the exchange for delivery against a futures contract. Because transport costs differ between locations, the exchange applies location differentials — and a hedger's real economics depend on the relationship between their own silo and the contract's delivery points.

Silo receipt

A transferable document issued by a registered storage operator confirming that a stated quantity and grade of grain is held in store at a specific location. Silo receipts are the instrument through which physical delivery against South African grain futures is settled — which is what ties the exchange price to the physical market.

Open interest

The total number of futures or options contracts in a delivery month that remain open — not yet closed out or delivered. Read alongside volume, it indicates whether a price move is being driven by new positions entering the market or by existing ones being unwound.

Instruments

Futures contract

A standardised, exchange-traded agreement to buy or sell a fixed quantity and grade of a commodity at a price agreed today, for a defined future delivery month. The exchange sets the contract size, grade specification, delivery months and delivery points, so the only variable negotiated between buyer and seller is price.

Option on a future

The right, but not the obligation, to take a position in an underlying futures contract at a set strike price before or at expiry. A call confers the right to go long, a put the right to go short. The buyer pays a premium; the seller receives it and carries the obligation. Options let a producer or end-user set a price floor or ceiling while leaving the other side of the move open.

Calendar spread

Simultaneously holding a long position in one delivery month and a short position in another of the same commodity. The trade expresses a view on the price relationship between the two months — the market's pricing of storage, financing and expected supply through the season — rather than on the flat price.

Rand-quanto contract

A JSE-listed derivative that tracks an international underlying — a metal, an energy product or a foreign index — but settles in rand at a fixed one-to-one conversion, so the holder takes the price exposure without the currency exposure. It gives a South African account access to global markets without a separate offshore allowance.

Single-stock future

A futures contract over an individual listed share. On the JSE these are used both to take directional positions and to hold equity exposure on margin, with the financing cost expressed in the difference between the futures price and the underlying share price.

Money and mechanics

Settlement price

The official end-of-day price the exchange determines for each contract month. It is the reference used to mark open positions to market, to calculate margin requirements, and as the price series quoted in market commentary. It is an exchange-determined valuation, not necessarily the last traded price.

Mark-to-market (MTM)

The daily revaluation of every open futures position against the exchange's official settlement price. Gains and losses are realised in cash each day rather than accumulating to expiry — which is why a futures account must be funded to meet daily movement, not only the eventual outcome of the trade.

Initial margin

The good-faith deposit the exchange requires before a position can be opened, sized to cover a plausible one-day adverse move in that contract. It is collateral held against performance, not a payment for the commodity, and it is returned when the position is closed. The exchange revises margin requirements as market volatility changes.

Variation margin

The daily cash flow that settles the mark-to-market move on an open position. If the market moves against a position, variation margin is called and must be met; if it moves in favour, variation margin is credited. Managing this cycle is core to running a hedge — a hedge that is working in the physical market can still consume cash on the futures leg.

Rollover

Closing a position in an expiring contract month and simultaneously reopening it in a later month, so exposure continues past expiry without triggering delivery. The cost or benefit of rolling depends on the price difference between the two months.

Implied volatility

The rate of price movement the market is pricing into an option, derived from its premium. It is the main determinant of what a hedge using options costs: the same price floor is cheaper to buy when the market expects a quiet season and dearer when weather or supply risk is elevated.

Pricing the local market

Basis

The difference between the local physical price at a specific location and the price of the relevant futures contract. Basis captures everything the futures contract does not: transport to or from the delivery point, storage, local quality, and regional supply and demand. A hedge placed on the exchange removes flat price risk but leaves basis risk with the hedger.

Import parity

The landed cost of bringing an equivalent tonne of grain into South Africa from an international origin — the world price plus freight, insurance, port handling, duties and inland transport to the destination. It acts as the practical ceiling on the local price: above it, buyers import rather than buy locally.

Export parity

The net price a South African seller could realise by exporting a tonne of grain — the world price at destination less freight, port and inland transport costs back to the local delivery point. It acts as the practical floor: below it, sellers export rather than sell locally. The band between export and import parity is where SAFEX prices normally trade.

Carry

The cost of holding physical grain over time — storage, insurance and the financing of working capital. When later delivery months trade at a premium sufficient to cover those costs, the market is said to pay carry, which rewards storing grain rather than selling it immediately.

Hedging

Short hedge (producer hedge)

Selling futures against a physical crop that is growing or already in store, so a fall in the market is offset by a gain on the futures position. It is the standard way a grain producer fixes a selling price ahead of delivery — and it caps the upside as well as the downside.

Long hedge (end-user hedge)

Buying futures against a future physical requirement, so a rise in the market is offset by a gain on the futures position. Mills, feed manufacturers and other end-users use it to fix an input cost ahead of purchase.

Phased pricing

Hedging a crop or a requirement in scheduled increments across the season rather than in a single decision, so the realised price converges on the season's average and the outcome depends less on the timing of any one trade.

The release calendar

SAGIS

The South African Grain Information Service, which publishes the official statistics on grain producer deliveries, imports, exports and stocks. Its weekly and monthly releases are the primary evidence of how much grain has actually moved in a season — as distinct from how much was forecast.

Crop Estimates Committee (CEC)

The South African committee that publishes the official sequence of area-planted and production forecasts through the season. Because its estimates are revised as the crop develops, CEC release dates are among the scheduled events most capable of moving SAFEX prices.
